My app was using OneDrive access with no problems for years and suddenly it does not work.
Your documentation says, re-direct Uri:
3 years ago, following a post in this forum that I started myself, I changed it to:
https://login.live.com/oauth20_desktop.srf
When I try to connect now the following error appears: "Socket error #10013. Access denied"
I have tried both options with no success.
Any suggestion?
